Almond tree named ‘Bennett-Hickman’

ABSTRACT

The invention provides a new and distinct variety of almond tree, named ‘Bennett-Hickman’, substantially as described and illustrated herein, which is somewhat similar to the ‘Nonpareil’ almond tree (unpatented), but which is distinguishable therefrom by possessing a heavier bloom, an extended bloom period, greener foliage that is retained for a longer duration of time, a sweeter kernel, with rare doubles, and a harvest period that runs approximately 14 days later than ‘Nonpareil’.

Latin name of the genus and species of the tree claimed: The tree claimed is known by the scientific name Prunus dulcis.

Variety denomination: The varietal denomination of the tree claimed is ‘Bennett-Hickman’.

BACKGROUND OF THE NEW VARIETY

The present invention relates to a new and distinct variety of almond tree, botanically know as Prunus dulcis, which will hereby be denominated by the cultivar name ‘Bennett-Hickman’, and more specifically to an almond tree that produces a crop for harvesting and shipment approximately mid-August under the ecological conditions prevailing in the Modesto area of the San Joaquin Valley of central California.

‘Bennett-Hickman’ was discovered in 1975 as a seedling growing adjacent to a windmill on the inventor's property located in Hickman, Calif., in the San Joaquin Valley. The variety has been observed to have an extended and profuse bloom period and heavy nut production, as compared to the non-patented ‘Nonpareil’ variety. Asexual reproduction of the tree has produced progeny that are consistent with the original specimen as to vegetative characteristics.

ORIGIN AND ASEXUAL REPRODUCTION

The variety was discovered by Jim Bennett as a volunteer seedling adjacent to a cultivated area of his property located in Hickman, Calif. After approximately 3 years of observation, during which the variety's unusually long bloom period and heavy yields relative to the non-patented ‘Nonpareil’ variety were noted, the original seedling was asexually reproduced in 1979 by collecting budwood from the mother tree to bud on ‘Nemaguard’ rootstock at a Nursery in Hughson, Calif. Approximately 45 specimens were inter-planted throughout an orchard of ‘Nonpareil’ trees and other commercial varieties. All of these trees have survived.

Reproduction by budding and grafting resulted in true-to-type progeny with respect to all tree vegetative and reproductive characteristics. These reproductions utilized ‘Nemaguard’ rootstock on which the present variety was compatible and true to the original tree in all respects.

The presently observed reproduced specimens are now in their 8th leaf.

SUMMARY OF THE VARIETY

The present variety was selected and tested because of its extended and profuse bloom period and heavy nut production and has the following outstanding and distinguishing characteristics when grown under normal horticultural practices in the Modesto area of the San Joaquin Valley of central California. Tree foliage is greener in color than the leaves of ‘Nonpareil’ and the harvest date of ‘Bennett-Hickman’ is approximately 14 days later than ‘Nonpareil’. Furthermore, the ‘Bennett-Hickman’ variety holds it leaves approximately 14 days longer than the ‘Nonpareil’ variety on an average year. Nut yield of the new variety is on average slightly greater than that of the ‘Nonpareil’ variety, and nut quality is comparable to ‘Nonpareil’. The variety blooms about 7 days earlier than ‘Nonpareil’, has an abundance of flowers along each fruiting branch, and continues to bloom about 7 days longer than ‘Nonpareil’. The extended blooming characteristics make it a very attractive pollinator for use with ‘Nonpareil’, as well as other varieties.

Molecular analysis of the S-allele controlling cross-incompatibility in almond testing was performed and indicates that the ‘Bennett-Hickman’ variety would be placed in the Thompson cross-incompatibility group. This means the variety is cross-compatible with most commercial California varieties including ‘Nonpareil’ (unpatented) and ‘Carmel’ (U.S. Plant Pat. No. 2,641). Field test crosses performed in 2009 provide additional confirmation of the cross-compatibility of ‘Bennett-Hickman’ with the ‘Nonpareil’ variety.

DETAILED BOTANICAL DESCRIPTION OF THE NEW VARIETY

Referring now more specifically to the pomological characteristics of this new and distinct variety of almond tree, the following has been observed under the ecological conditions prevailing in Hickman Calif., which is near Modesto, Calif. (San Joaquin Valley). Observations were performed just prior to the harvest stage on Aug. 18, 2009 and at the flowering stage on Feb. 16, 2010.

All major color code designations are by reference to the Inter-Society Color Council, National Bureau of Standards. Common color names are also used.

TREE

-   -   -   Origin.—The present variety was discovered as an open             pollinated seedling of unknown parentage growing within the             cultivated region adjacent to the inventor's orchard which             is located in Hickman, Calif.         -   Vigor.—Considered very vigorous.         -   Hardiness.—Considered hardy under typical San Joaquin Valley             climatic conditions.         -   Chilling requirement.—Considered normal under prevailing San             Joaquin Valley climatic conditions.         -   Tree form.—Considered spreading and upright in its growth             pattern. For observed trees that were 8 years old, when             grown on ‘Nemaguard’ rootstock, the height of the trees were             approximately 15 feet. Further, these same trees had a crown             spread of approximately 22 feet.         -   Productivity.—Considered very productive. For trees that are             at least 8 years old, with currently acceptable planting             densities, approximately 3000 pounds of almonds on average             are harvested per acre.         -   Regularity of bearing.—Considered regular for the species.             No significant alternate bearing has been observed.         -   Fertility.—Self-sterile. The new variety must be cross             pollinated by other almond varieties, including ‘Nonpareil’             (unpatented) and ‘Carmel’ (U.S. Plant Pat. No. 2,641).         -   Date of harvest.—Sep. 7, 2009, approximately 14 days later             than ‘Nonpareil’ when irrigated using micro-sprinklers.

I claim:
 1. A new and distinct variety of almond tree, named ‘Bennett-Hickman’, substantially as described and illustrated herein, which is somewhat similar to the ‘Nonpareil’ almond tree (unpatented), but which is distinguishable therefrom by possessing a heavier bloom, an extended bloom period, greener foliage that is retained for a longer duration of time, a sweeter kernel, with rare doubles, and a harvest period that runs approximately 14 days later than ‘Nonpareil’.
